USB On-The-Go, often abbreviated to USB OTG or just OTG, is a specification first used in late 2001 that allows USB devices such as digital audio players or mobile phones to act as a host, allowing other USB devices such as USB flash drives, digital cameras, mice or keyboards to be attached to them. Use of USB On-The-Go allows those devices to switch back and forth between the roles of host and client devices. For instance, a mobile phone may read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer.
In other words, USB On-The-Go introduces the concept of a device performing both master and slave roles – whenever two USB devices are connected and one of them is a USB On-The-Go device, they establish a communication link. The device controlling the link is called the master or host, while the other is called the slave or peripheral.

Tian is far better than Yun if you need analog I/O.
Better if you need the extra two bits of resolution, but not better if 10 bits is good enough and you need more channels.

eMMC Flash 4 GB.
Not the same as an SD card: it's smaller, and not removable. That means you can't swap out the card to log more data, copy the files to another computer, or prevent wearing out frequently updated files.
Increased raw power is enticing: but not every application needs maximum processing power, and with the increased power comes some trade-offs that might eliminate it from some some applications.

It is true.
On other side micro SD slot has reliability problem, we saw so many threads here already.

Thats what I meant with the microSd. But theres the usb host for flash drives.
New Arduino Tian come with two standard antenna connector, one for 2.4 GHz and an other for 5 GHz.
extended wifi range could be easily by use antenna. 24 dBi antenna will make wifi range from 100m to 1600m.

Friis Transmission Formula with Propagation Law
R = Maximum range for communication link
N = Propagation Law (N=2 for line-of-sight, N=4 for urban environments)
PT= Transmit power
GT= Total antenna gain
λ = Wavelength
PR= Receiver sensitivity
FM= Fading margin
if in urban environments;-
Every 12 dBm receiver sensitivity gain will be double the distance.
Every 12 dBi antenna gain will be double the distance.
Every 12 dBm Transmitter power gain will be double the distance.
in line of sight environments;-
Every 6 dBm receiver sensitivity gain will be double the distance.
Every 6 dBi antenna gain will be double the distance
Every 6 dBm Transmitter power gain will be double the distance.

Wow, a beautiful board. I wonder if they will improve the bridge library. And I didnt see a microsd socket.

Arduino.org provides a new library called "Arduino Ciao" that runs on the Yun. I knew it at last LinuxCon in Dublin few days ago. I tried ciao and it seems to be faster and simplier than the standard bridge. Ciao is also plugin based, but at the moment it supports few protocols though.
